Cannon & Serrano to be Widened

The City of Orange will be using funds from Measure M to widen the intersection at Cannon St and Serrano Ave. The Orange County Transportation Authority (OCTA) awarded funding for 11 projects to improve and widen busy streets and intersections throughout Orange County. Measure M will contribute $108,000 towards this initiative with the OCTA matching an additional $37,000.

Details regarding the improvement have not been provided but the City of Orange has previously recommended that Cannon Street @ Serrano Avenue intersection requires reconstruction of the westbound approach of Serrano Avenue to provide for triple westbound left turns. However, this improvement would require Cannon Street to be widened in the southbound direction to accommodate a triple left turn lane. Impacts to residences would be required to implement this improvement measure. Previous traffic studies have have noted that Cannon Street between Serrano Avenue and Taft Avenue operate at unacceptable levels.

Cannon Street is a four-lane, divided roadway oriented in the north-south direction. On-street
parking is generally not permitted along this roadway within the vicinity of the Project. The posted
speed limit on Cannon Street is 45 mph north of Santiago Canyon Road and 40 mph south of
Santiago Canyon Road. Traffic signals control the study intersections of Cannon Street at Serrano
Avenue, Taft Avenue and Santiago Canyon Road.

Both Cannon and Serrano used to be dead end streets where Cannon ended at Loma (slightly North of Serrano) and Serrano stopped at the end of Mabury Ranch (Orange Park Blvd). Now these streets are used by many commuters to navigate to the 91, Anaheim Hills Yorba Linda, and Riverside creating traffic congestion in this area that didn’t previously exist.

Voters first approved a half cent sales tax in 1990 for 20 years. With the $4 billion, transportation improvements were made, including adding 192 freeway lane miles, improving 170 intersections and 38 freeway interchanges, and implementing Metrolink service in Orange County. In 2006 voters renewed the sales tax for transportation improvements for another 30 years. By the year 2041, the OC Go Transportation Investment Plan program plans to deliver over $13 billion worth of transportation improvements to Orange County. Major improvement plans target Orange County freeways, streets and roads, transit and environmental programs.
